Where we compared lists, they were similar on revolutionary sources such as printing press, television or the one we were writing a book on in the 1970s : computerised telecomunications. But my father;' list included trains and other transport revolutions as joyful innovations in how people communicate and value freedom of living to the full on planet earth.

So it was dad declared the train that turned the invention of steam engine into industrial revolution. Previously you had to live near water or rieed horses to move more than 20 miles than where you were born. This made most people subservient to the biggest local boss. A nice system for bosses but not an entrepreneurially free and happy one for most families and peoples. It was also the train that began the city as where more people populated their productivity than the rural areas, with huge changes to how any place valued its future possibilities, especially for and by youth.

This exercise became the framework for our 1984 book (published after 12 years of debates in The Economist) on The Entrepreneurial Revolution of the net generation valuing telecommunications as the most valuable and urgent worldwide change the human race had ever experienced

If you work on your list of revolutions, you may enjoy graduating to a second exercise. How do you couple communications properties so that they flow every way round instead of having one bossy top.

COUPLED COMMUNICATIONS

Here is the sort of basic checklist that I would suggest every chiuld is literate in before adolescence

Communications is how your life is spent as a producer as well as how it is spent as a consumer

Commuincations is how collaborative, open and grounded in local diversity you map the world as well as how competitive, possessively closed and globally powerfully professions rule

Communications is how smart we mediate and educate with the commons as well as how much time we spend celebrating entertainments stars, gratuitous pleasures and being told by public servants that they need to administer state secrets.

If all of this sounds theoretical I had ho[e the opposite that it would heighten your curiosity. It turns out that when you address such valuable innovation questions as what purpose of a particular global sector would most sustain future generations and so grow worldwide communities in the information millennum of being more interconnected than separate, people explore wholly different purposes depending on how much they have rehearsed the entrepreneurial possibilities of COUPLED COMMUNICATIONS

PS What started our belief in computerized telecommunications being the greatest communications revolution of all was being involved from 1972 in student experiments with digital learning networks. After 12 years of debating impacts of these with readers of The Economist, the coupled communications of global village networks became most valuable to debate

opportunity of global village age is best for world searches whilst sustaining deepest local diversity of application

risk of global village age is big brother powering over people neglecting how locally diverse each community's next great sustainability/innovation challenge needs to be

unless the world's biggest organisations valuing have the most responsible global market purposes as valued by youth representing the future generations, our species my become the next dodo. To map how to value this massive collaboration challenge, look at www.valuetrue.com

Dad (Norman Macrae) created the genre Entrepreneurial Revolution to debate how to make the net generation the most productive and collaborative . We had first participated in computer assisted learning experiments in 1972. Welcome to more than 40 years of linking pro-youth economics networks- debating can the internet be the smartest media our species has ever collaborated around?

1972: Norman Macrae starts up Entrepreneurial Revolution debates in The Economist. Will we the peoples be in time to change 20th C largest system designs and make 2010s worldwide youth's most productive time? or will we go global in a way that ends sustainability of ever more villages/communities? Drayton was inspired by this genre to coin social entrepreneur in 1978 ,,continue the futures debate here
